Hi there,
I would like to know: what does the meaning "warui" is in this context please? I know the litteral meaning but I wonder if it isn't to show that the character is wrong (he didnt do the right thing in situation). That's during a sitution of war and the other person who talks in his sister. I also have this prequel to help:http://imgur.com/DUtPS
And I would like to know what is also the meaning of the last sentence too where the character seems dote upon something.
Thanks for your answers

So the character is wrong about something? By the way, what is written before this sentence "he is wrong or his sister is wrong?"
Don't know. I think it involves the picture which is a prequel. By the way can you tell me what is written? http://imgur.com/DUtPS

"It's alright, Scolastica."
Although being aware of his unpleasant emotion* toward his sister, in order to wipe it out, Benedict talked to her as softly as usual.
"I'll take care of you. I'll definitely defeat everything you're afraid of."
